Quick Charge
Quick Charge (QC) is a proprietary charge controller#Charging protocols, battery charging protocol developed by Qualcomm, used for managing power delivered over USB, mainly by communicating to the power supply and negotiating a voltage. Quick Charge is supported by devices such as mobile phones which run on Qualcomm system-on-chip (SoCs), and by some chargers; both device and charger must support QC, otherwise QC charging is not attained. It charges batteries in devices faster than standard USB allows by increasing the output voltage supplied by the USB charger, while adopting techniques to prevent the battery damage caused by uncontrolled fast charging and buck converter, regulating the incoming voltage internally. Many chargers supporting Quick Charge 2.0 and later are wall adaptors, but it is implemented on some automobile auxiliary power outlet, in-car chargers, and some battery charger#Power bank, power banks use it to both receive and deliver charge. Quick Charge is also us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reverse-engineering
Reverse engineering (also known as backwards engineering or back engineering) is a process or method through which one attempts to understand through deductive reasoning how a previously made device, process, system, or piece of software accomplishes a task with very little (if any) insight into exactly how it does so. Depending on the system under consideration and the technologies employed, the knowledge gained during reverse engineering can help with repurposing obsolete objects, doing security analysis, or learning how something works. Although the process is specific to the object on which it is being performed, all reverse engineering processes consist of three basic steps: information extraction, modeling, and review. Information extraction is the practice of gathering all relevant information for performing the operation. Modeling is the practice of combining the gathered information into an abstract model, which can be used as a guide for designing the new object or syst ...

Samsung
Samsung Group (; stylised as SΛMSUNG) is a South Korean Multinational corporation, multinational manufacturing Conglomerate (company), conglomerate headquartered in the Samsung Town office complex in Seoul. The group consists of numerous affiliated businesses, most of which operate under the Samsung brand, and is the largest (business conglomerate) in South Korea. Samsung has the world's List of most valuable brands, fifth-highest brand value. Founded in 1938 by Lee Byung-chul as a trading company, Samsung diversified into various sectors, including food processing, textiles, insurance, securities, and retail, over the next three decades. In the late 1960s, Samsung entered the electronics industry, followed by the construction and shipbuilding sectors in the mid-1970s—areas that would fuel its future growth. After Lee died in 1987, Samsung was divided into five business groups: Samsung Group, Shinsegae Group, CJ Group, Hansol Group, and JoongAng Ilbo, JoongAng Group. K ...

Standby Mode
Sleep mode (or suspend to RAM) is a low power mode for electronic devices such as computers, televisions, and remote controlled devices. These modes save significantly on electrical consumption compared to leaving a device fully on and, upon resume, allow the user to avoid having to reissue instructions or to wait for a machine to boot. Many devices signify this power mode with a pulsed or red colored LED power light. Computers In computers, entering a sleep state is roughly equivalent to "pausing" the state of the machine. When restored, the operation continues from the same point, having the same applications and files open. Sleep Sleep mode has gone by various names, including ''Stand By'', ''Suspend'' and ''Suspend to RAM''. Machine state is held in RAM and, when placed in sleep mode, the computer cuts power to unneeded subsystems and places the RAM into a minimum power state, just sufficient to retain its data. Because of the large power saving, most laptops automatically ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wireless Power Consortium
The Wireless Power Consortium (WPC) is a Multinational corporation, multinational technology consortium formed on December 17, 2008. WPC is a virtual corporation with administrative offices in Washington, DC. Its mission is to create and promote global adoption of its interface standards: Qi (standard), Qi for small, mobile electronics, and Ki for wireless power in the kitchen. It is an open membership of Asian, European, and American companies, working toward the global standardization of wireless charging technology. The Wireless Power Consortium was started by Fulton Innovation, a 100% subsidiary of Alticor, parent company of Amway. The original motivation was to power a portable water purifier, sold by Amway, called eSpring, for which the wireless power transfer technology called eCoupled was created. On Nov 26, 2008 Fulton Innovation released "The Base Spec: Low Power Specification Guide for Partnered Product Development, Revision 0.9". Buoyed by the acquired intellectual pr ...

Qi (standard)
Qi ( ) is an open standard for inductive charging developed by the Wireless Power Consortium. It allows compatible devices, such as smartphones, to receive power when placed on a Qi charger, which can be effective over distances up to 4 cm (1.6 in). Devices that implement the optional Magnetic Power Profile for magnetic attachment and alignment may be labelled Qi2 ( ). Qi version 1.0 was released in 2010; by 2017, it had been incorporated into more than 200 models of smartphones, tablets, and other devices. In December 2023, 351 manufacturers were working with the standard, including Apple, Asus, Google, Huawei, LG Electronics, Samsung, Xiaomi, and Sony. , the current version of the Qi specification is 2.1., which incorporates Apple's MagSafe technology to enhance wireless charging through magnetic alignment. The current standard supports charging speeds of up to 15 watts and aims to improve compatibility across devices from various manufacturers. Naming The name Qi () means ...

Programmable Power Supply
A power supply is an electrical device that supplies electric power to an electrical load. The main purpose of a power supply is to convert electric current from a source to the correct voltage, current, and frequency to power the load. As a result, power supplies are sometimes referred to as electric power converters. Some power supplies are separate standalone pieces of equipment, while others are built into the load appliances that they power. Examples of the latter include power supplies found in desktop computers and consumer electronics devices. Other functions that power supplies may perform include limiting the current drawn by the load to safe levels, shutting off the current in the event of an electrical fault, power conditioning to prevent electronic noise or voltage surges on the input from reaching the load, power-factor correction, and storing energy so it can continue to power the load in the event of a temporary interruption in the source power (uninterruptible p ...

USB PD PPS
The initial versions of the USB standard specified connectors that were easy to use and that would have high life spans; revisions of the standard added smaller connectors useful for compact portable devices. Higher-speed development of the USB standard gave rise to another family of connectors to permit additional data links. All versions of USB specify cable properties. Version 3.''x'' cables, marketed as ''SuperSpeed'', added a data link; namely, in 2008, USB 3.0 added a full-duplex lane (two twisted pairs of wires for one differential signalling, differential signal of serial data per direction), and in 2014, the USB-C specification added a second full-duplex lane. USB has always included some capability of providing power supply, power to peripheral devices, but the amount of power that can be provided has increased over time. The modern specifications are called ''USB Power Delivery'' (''USB PD'') and allow up to 240 watts, with or without data communications capabili ...
